Thank you for checking guys... VERY MUCH!!
Good to know the real world measurements.
For those that are reading this... we are talking about the Arctic Cat 3" pitch, 153" long Power Claw, 2.25" tall lug tracks. Both Jkinzer and KAWGRN are running the 8 tooth, 3" pitch PPD drivers (avail from SLP, Whal Bros, and Carls). These are standard style, involute drivers and are very cost effective [$140/pair]
With the 8-Tooth, 3" pitch drivers in there and single ply track.... 5/8 of an inch clearance at the top 3/4" at the front (on a dragon with no front cooler).... not bad.
The 7 tooth, 3" pitch should give me just under 1/2" (.48') more clearance all around than the 8 tooth 3" pitch.
If I can get this 1.125" at the top and 1.25 at the front of the tunnel, I'll be VERY happy!
My only concern here is, how close the inside of the track will come to the upper cross tube of the front swing arm with the 7 tooth 3" pitch bringing the inside of the track a little more than 1/4" (.28) closer to this top tube. HMMM...
With the turbos, you guys shouldn't notice a whold lot of drag unless you were riding in very deep high moisture snow (like we get on the coast)
I'm working with Robbie at Avid right now to come up with a 7 tooth driver that is compatible with the slightly different drive nub arrangement on the Arctic Cat Power Claw tracks.... I'll keep you in the loop.
